The best smartwatches can do more than show notifications on your wrist. They're everything in one: a fitness tracker, a wallet and in some cases, even a phone.
A smartwatch can even save your life with elevated heart rate alerts and automatically connect you to emergency services if you fall. Electrocardiogram (ECG) and blood oxygen (SpO2) readings are perks of certain premium models, too. The former detects signs of atrial fibrillation, while the latter is a good indicator of respiratory health.

But the best smartwatches do all these things better than others. Some have huge numbers of apps you can download, and some have batteries that will barely last a day, while others can go nearly a week on a charge. And of course there's style: The best smartwatches can be customized, from their straps to their faces, to best fit with your personality.
See all of the best smartwatches below.
What is the best smartwatch?
After testing dozens of the best smartwatches, our top pick is the Apple Watch Series 5, which has a huge, always-on display, built-in compass, and all of the advanced health features we loved about the Series 4.
The Apple Watch 3 remains a very good value, too, although our early Apple Watch Series 6 review and Apple Watch SE review indicate these standings could change. That said, many of the Watch 6 upgrades have come over-the-air to the Series 3 and Series 5 via watchOS 7.
Samsung's new Samsung Galaxy Watch 3 is a worthy Apple Watch contender — in fact, it's the best smartwatch for Android users. It offers a rotating bezel, plus a larger display with slimmer bezels. It also introduces some life-saving features like FDA-approved ECG tracking and trip detection, all wrapped up in a stylish shell.
We're also keeping tabs on the Fitbit Sense ($329) and Fitbit Versa 3 ($229), coming late September. With the Fitbit Versa 2 being phased out, one of Fitbit's new offerings will likely replace it on this list.

The Apple Watch Series 5's always-on display makes a meaningful difference in user experience, especially when working out. Now when you glance at your wrist, you'll always be able to tell the time, with the Apple Watch automatically adjusting to the conditions around you with the help of an ambient light sensor. That always-on display doesn't drain the watch's battery, either, though you'll still want to charge your Apple Watch nightly, as it lacks the multiday battery life that other smartwatches offer.
Apple's latest watch also includes a built-in compass, which comes in handy while hiking or star-gazing, and also makes Maps more useful by showing you which direction you're facing at all times. Series 5 looks identical to Series 4, but the newer model comes in fresh finishes — titanium and ceramic — and offers the same advanced health features we loved in the Series 4. This is the best smartwatch you can buy.

The Samsung Galaxy Watch 3 is one of the most stylish smartwatches around, and one of the most functional, too. It's available in two sizes — 41 and 45 mm — as well as in LTE variants, so you can leave your smartphone at home. The Galaxy Watch 3's rotating bezel makes navigating the watch's interface easy, while access to thousands of watch faces lets you customize the display to your liking.
Although the Galaxy Watch 3 has a shorter, 2-day battery life compared to the original Samsung Galaxy Watch, it introduces more music storage, FDA-approved ECG tracking and trip detection. Of course, you'll get Samsung Pay for contactless payments, and some good fitness features too. Like the first Galaxy Watch, the Galaxy Watch 3's biggest setback is that Samsung's app store is limited compared to Apple's, but Tizen is catching up.

Starting at $199, the Apple Watch Series 3 is a more affordable smartwatch option than the Series 5 for iPhone users. The size options are smaller. bezels are thicker on the older model, and you won't get the newer watch's ability to detect atrial fibrillation with an ECG app.
However, when you compare the Apple Watch Series 5 vs Apple Watch Series 3, you'll find you don't sacrifice too much for the older version's lower price. You still get a heart rate monitor, GPS, 8GB of storage with offline support for Apple Music playlists. This watch is also water-proof if you like to track your swims, and many of the best software features found in the Apple Watch Series 5 are also found in the Series 3, thanks to the watchOS 6 Apple released last year. Check out our Apple Watch Series 3 vs. Fitbit Charge 4 face-off to see the benefits you'll get with Apple's smartwatch over a traditional fitness tracker, too.

As good as the Apple Watch is, the Galaxy Watch Active 2 can give Apple's smartwatch a run for its money. Samsung's watch works with both Android (and to a lesser extent) iOS smartphones, and features GPS, a heart rate monitor and LTE (for a premium). It also can automatically track your activity and sleep. (It's much better at the former task than the latter.)
The Galaxy Watch Active 2's circular design is visually appealing, whether you get the 40mm or 44mm model. Based on Samsung's Tizen operating system, this Galaxy Watch boasts other useful features as Samsung Pay, onboard music via Spotify and heart health features. That includes a forthcoming ECG feature that recently earned FDA approval. But the biggest reason why the Galaxy Watch Active 2 is one of the best smartwatches for Android users is its excellent battery life.

Fitbit's Versa 2 is a refined upgrade from the original Versa that adds built-in Alexa and more advanced sleep-tracking features, especially now that Fitbit has rolled out a software update that enables a feature to monitor blood oxygen saturation levels. (That data's helpful for identifying conditions like sleep apnea.) Throw in multi-day battery life, and we think the Versa 2 is the best smartwatch if you're looking for a way to monitor your sleeping habits.
As one of the best Fitbits, the Versa 2 works with both iOS and Android and costs less than $200, which makes it a great value. Fitbit added a Spotify app to the Versa 2, so you can control music playback from your wrist. However, you can't download Spotify playlists to the watch for offline listening. The Versa 2 also lacks on-board GPS.

Garmin took the best features of its Vivoactive 3, the best smartwatch for fitness, and made them even better with the $349 Vivoactive 4 and 4S. The watch now comes in two sizes, 40mm and 45mm, to offer a better fit for most people, and includes both Garmin Pay and music storage out of the box (instead of having to pay more for premium features like with the Vivoactive 3).
The Vivoactive 4 also offers animated on-screen yoga and Pilates workouts to help you improve your poses. A new pulse ox sensor measures your blood oxygen level and gives you more detailed sleep insights. All of that plus 7-day battery life makes the Vivoactive 4 our favorite smartwatch for fitness buffs.

You don't necessarily have to pay big bucks to get a capable smartwatch with fitness-tracking feature. The ultra-affordable Amazfit Bip costs less than $80, yet works with iOS and Android and comes with GPS and a heart rate monitor.
Fitness-tracking features are pretty solid, and the Bip's transflective color display is easy on the eyes and doesn't drain the battery. Speaking of battery life, you can expect around 45 days of normal usage — we used the Amazfit Bip for two weeks before the battery dipped below 50%.
Other functionality is limited: You can select only from five different watch faces, and can only view, and not respond to notifications from the watch itself. But if you're in the market for a smartwatch that costs less than $100, this is the model to get.

Wear OS simply isn't polished enough to measure up against the best smartwatches from Apple and Samsung. But if you insist upon a Wear OS device, Fossil's Gen 5 smartwatch is the one to get, thanks to a stylish, sophisticated look. The Gen 5 also eliminates the most glaring performance lag we saw in past Wear OS watches, thanks to 1GB of RAM, and customizable battery modes also make this smartwatch worth a look.
You're not going to get the fitness and heart health features you'll find on the Apple Watch and the Galaxy Watch Active. And the Gen 5's Spotify app can't store music offline — also a disadvantage. But this smartwatch remains the best that Wear OS has to offer.

How to pick the best smartwatch for you
When looking at the best smartwatches for you, you're somewhat limited by the smartphone you own. If you want an Apple Watch, for instance, you'll need to have an iPhone. And while Wear OS watches work with both Android and iPhones, you get far less functionality when not connected to an Android device.
Samsung's smartwatches offer the greatest in terms of cross-functionality, but even here, Android phone owners will get more in terms of replies to notifications and the ability to make and receive phone calls.
After that, when picking a smartwatch, you also want to get one that fits your wrist comfortably. Those with smaller wrists may find larger smartwatches — ones with case sizes larger than 44mm — to be too bulky and cumbersome to wear.
After that, you want to find a smartwatch that fits your style. Although the Apple Watch is limited to one shape, you can purchase it in different finishes. Samsung's smartwatches offer a little more choice, while Wear OS watches, which are made by a number of companies including Fossil, Skagen, Kate Spade, Moto, Tag Heuer, Diesel, and others, give you many more options when it comes to their design.
How we test the best smartwatches
We test every new smartwatch to gauge its design and comfort. If it’s not stylish and comfortable enough to get you from an early morning workout to the office to a night out, you probably won’t wear it every day. Most smartwatches are also fitness trackers, so we put all of its sensors to the test, from step counts to heart rate to GPS (when applicable).
We install apps and use them to see if the device’s app store is robust enough to elevate it to smartwatch status. If the watch has built-in LTE, we test cellular connectivity and call quality to make sure the device can actually stand on its own without a smartphone nearby.
And we measure battery life using everyday scenarios — including workouts, using apps, and getting notifications — to make sure you can get through an entire day without needing to charge up.
